POSITIVE SHUTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 340,528, dated April 20, 1886.

' Application filed March 6, 1884. Serial No. 123,200. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES B. RUMsnY, of Homer, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Positive Shuttle-Motions for Looms, and I do hereby declare the following to be a full, clear, and exact deiscrip'tion of the same, reference being had to the'accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

Myinvention relates to that class of shuttlemotions for looms in which the shuttle is carried back and forth by powerful acting mech anism in contradistinction to being thrown; andit consists in certain details of construction and combinations of parts, which I will first describe, and then point out particularly in the claims at the end of this specification.

Referring to the accompanying drawings, Figure 1 is a top View of my invention; Fig. 2, a side elevation of the same; Fig. 3, a bottom plan View of the shuttle-frame and bobbin, and Fig. 4 a detailed view showing means for connecting the bobbin to the shuttle-frame.

A A indicate two shuttlecarrier arms arranged in the same horizontal plane and adapted to be operated toward and from each other.

B represents the shuttlefranle, and O the bobbin carried thereby.

The shuttle-frame may be made in parts, though it is preferably formed in one piece, with a slot, 1), extending laterally through it for the admission of the bobbin, with elongated squared projections b b at opposite ends, and with a lateral arm, I)", extending out from the bottom portion, and provided with opposite inclines b b and a centralrib or stud, 6 as shown,

The bobbin 0 is held in place within the shuttle-frame by means of a removable vertical pin or bolt, a, passing down through it and through the upper and lower parts of the shuttle-frame. The lower end of this bolt is squared, and fits into a corresponding opening or step in the lower part of the shuttle-frame, so as to keep it from turning, while its upper end, which may be either round or square,

though it is preferably made round, is provided with a peripheral groove, 0, with which a slide, cl, working laterally in the upper part of the shuttle-frame and pressed inward by a spring, (1, is adapted to engage. I

To secure the bobbin in place, it is inserted in the slot of the shuttle-frame with its aperture or bore in line with the opening in the frame; the lateral slide is then drawn out by means of its spring, and the pin or bolt 0 inserted and pressed down till its lower squared ocj I end is seated in the lower opening. By the time the bolt has reached its lowest point the groove in its upper end has arrived opposite the slide, and the spring behind the latter causes it to automatically engage with it, thus locking the pin securely in position. By a reverse order of operation the bobbin is taken out.

Each of the shuttle-carrier arms is made hollow, or provided with a squared socket in its end, in which the corresponding end projection of theshuttleframe is adapted to slide when the parts are brought together. It is further provided with a pawl, E, hinged ate, and having its forward beveled shouldered end,c, arrangedin line with the corresponding incline, b or b*,on the shuttle-frame, as shown in Figs. 1 and 2. A spring, 0 operates upon each of the pawls to keep it normally depressed, and a stop, 0, acts upon the rear end of the pawl to limit its downward movement.

The hollow shuttle-carrying arms are operated intermittingly in opposite directions by any suitable positively acting mechanism, though I prefer to use that described in Letters Patent No. 323, 738, granted to me August 4, 1885, which has been found by experiment to be admirably adapted for the purpose.

, From the above description the co-operation of the parts will be readily understood.

To connect the shuttle-frame to one of the carrier-arms, it is only necessary that oneof the elongated ends of the shuttle-frame should be inserted in the socket in the end of said arm and pressed forward, whereupon the beveled end. of the spring-pawl willstrike incline If, for instance, of the shuttle-frame, ride first up said incline and then over the central rib or stud, b and its shoulder will become engaged with the latter. If, now, the arm ear- IOO rying the shuttle be made to approach the other co-operating carrier arm, the projecting end of the shuttleframe will first enter the socket in the end of said last-mentioned arm, while the spring-paw1 of the latter will ride up the incline b, release the end of the other pawl from the central rib or stud, and become itself engaged therewith. Then, upon a recession of the two arms from each other, the shuttle will be carried by the arm whose pawl is in engagement. Each time the arms approach, therefore, the shuttle is transferred automatically from one to the other, and remains firmly and securely engaged therewith till again released and transferred.

I have designed thes'edevices for use in carrying the shuttle in a positively-acting wireweaving loom; but it is evident that they may be employed in connection with looms of other classes.

Heretofore bobbins for wire-weaving looms have been mounted in the shuttle-frame on an axis parallel to the line of movement of the latter; but in order to effect the uniform unwinding ofwire from such bobbins one or more pairs of rollers arranged about midway of the bobbin and to one side thereof have been re quired to be employed;

In. another style of prior shuttles the wire has been withdrawn from the center of a conical coil arranged within the shuttle-frame, and then passed through between a series of swaging-rolls for the purpose of taking the twist out of it produced from its mode of withdrawal from the coil.

In my invention, it will be observed, the bobbin is mounted within the shuttle-frame on a pivot which passes vertically through the latter at substantially right angles to the line of movement of the shuttle-frame, the effect of which construction is to enable the wire to be withdrawn without being at all twisted during the operation, and to obviate the necessity of employing supplemental devices either to guide the wire as it is withdrawn or to swage it. By thus simplifying the construction the article is considerably cheapened, yet equally as effective.

Having thus described my invention, I claim as new-- 1. The shuttle-frame having the extended end projections and the lateral arm provided with the opposite inclines and the central rib or stud, and having the elongated slot formed through it transversely, in combination with the bobbin arranged within said slot and mounted upon a pivot passing vertically through the shuttle-frame, substantially as described.

2. The combination, with the shuttle-frame having the extended end projections and the lateral arm provided with the opposite inclines and the central rib or stud, and having the elongated slot formed through it transversely, of the bobbin arranged within the said slot and mounted upon a pivot passing vertically through the shuttle-frame, and the shuttIecarrying arms having the sockets in the ends, and the pawls on the sides provided with springs for operating them, substantially as described.

3. The shuttle-carrier arms, each having the socket in its end, the pawl on its side, the spring for depressing the outer end of the pawl, and the stop for limiting the downward movement of the pawl, in combination with the shuttle-frame having the extended ends, and the lateral arm having the opposite inclines and the central rib or stud, substantially as described.
